EJECTOR FOR VENDING-MACHINES.

Specification of Letters Patent.

Application filed February 6, 1908. Serial No. 414,532.

To all 'whom it may concern:

Be it known that we, ALBERT D. Gnovnn, of Malden, county of Middlesex,and State of Massachusetts, and EARL E. BARBER, of Boston, county ofSuffolk, and State of Massachusetts, citizens of the United States, haveinvented certain new and useful Improvements in Ejectors forVending-lll'achines, of which the following' is a specification,rei'erence being had to the drawings accompanying the same and forming apart thereof.

Our invention relates to a device for ejecting packages of goods from acoin controlled vending machine.

The object of our invention is to provide a yielding goods ejector,means to prevent the ejector from ejecting more than one package ofgoods at each operation of the coin slide to which it is attached, toprevent t-he ejector from coming in Contact with the receptaclecontaining the goods, and means for locking the coin slide in its inmostposition when the last package of goods has been ejected.

In the drawings accompanying this speciication and forming a partthereof-Figure 1 is a perspective of the goods ejector detached from theplunger and coin slide. Fig. 2 is a sectional elevation of the goodsejector attached to the plunger and coin slide, a section of the framein which same is mounted, and a partial section oi the stack or goodsreceptacle. Fig. 3 is a sectional elevation of the same parts with theplunger pushed inward to a point where the goods ejector contacts withthe package ol goods in the receptacle; and Fig. 4lis a sectionalelevation on the same line as Fig. 2, with the plunger at its inmostposition, the last package of goods ejected, and the plunger and slidelocked against operation.

In the drawings, 1 represents the trame in which the coin slide 2 ismounted to slide freely in and out. The coin slide 2 has a block 3attached to its inner end and a plunger 4 mounted in said block 3. Thespring 5 is mounted upon the rod 6 which is secured at the point 7 inthe portion 8 of the frame 1, the spring 5 serving to return the coinslide and plunger to their normal position after a package of goods hasbeen ejected. To the upper edge of the block 3 the goods ejector 9 isyieldingly pivoted by means of the pivot 10 in such manner as topartially rotate upon said pivot 10, and is kept in its uppermostposition by means of a spiral spring 11 which is wound upon and one endof it attached to the pivot 10, its free end contacting against theunder side of the goods ejector 9. The portion 12 limits the upwardmovement of the goods ejector.

13 is a guide pivoted to the goods ejector 9 by means of the pivot pin14 and is arranged to partially rotate upon said pivot. The free end l5projects through the opening 16 attached to the bottom of the goodsreceptacle-17. This opening 16 serves to keep the portion 13 inalinement and keep it from dropping downwardly when the plunger ispushed in as shown in Fig. 3. The portion 13 is so arranged and formedas Patented Jan. 31, 1911.l

to lie upon the surface 18 when the plunfrer.,

and coin slide are at their outmost position so that when the plungerand goods ejector are moved inwardly the outer end of said portion 13will contact with the lower wall of the opening 16 and hold the parallelportion 20 upwardly against the underside of the lower-most package ofgoods, as shown in Fig. 3. The vertically projecting part 19 willcontact with the forward edge of the goods to push it outwardly from thestack. The contact of the parallel portion 2O with the under side of thegoods prevents the ejector from being thrown upwardly to contact withthe inner wall of the goods receptacle. An opening 21 is formed in thegoods ejector 9, designed to receive the lower end of a sliding cam 22which is pivoted in a slot in the weight 23 by means ot' the pivot 24.The weight 23 rests upon the uppermost package of goods and follows downwith the goods as they are ejected. Vhen the last package of goods isejected the point 22 will drop downwardly below the lower surface of theweight 23 andthe hook portion 22 catch in the opening 21, thus lockingthe goods ejector in its most inward position.

We do not limit ourselves to the exact form of yielding goods ejectoro1' guide, nor to the form of locking device shown, as the form or shapemay be varied without departing from the spirit of our invention.

lVhat we claim is-- l. In a goods ejector for vending machines and thelike, an ejector consisting of two portions yieldingly pivoted to eachother; a block secured to a plunger, the inner portion of the yieldingejector being yieldingly pivotedV thereto; a spring for maintaining theinner portion in its normal upward position; and means for guiding theouter portion of the goods ejector to limit its contact to the lowermostpackage of goods, and to eject the same from the goods receptacle.

2. A goods ejector `for vending machines and the like, comprising twoyieldingly pivoted portions, the inner portion being yieldingly pivotedto a block secured upon a slidable plunger; said plunger; means forholding the inner portion in its normal upward position, the outerportion being rotatively pivoted to the inner portion in such manner asto contact with the under side of the lowermost package of goods toprevent the ejector from cont-acting with or ej ecting more than onepackage of goods at each Vcomplete movement of the plunger' and ejector.

3. A goods ejector for vending machines and the like, comprising tworotatively pivoted portions; a block secured to a slidable plunger; saidplunger, the inner portion of said plunger being rotatively pivoted tosaid block; a spring co-acting with said block and said inner portion toretain it in its normal upward position; the outer portion of theejector comprising a guide surface and an ejector surface; the guidesurface serving to limit the contact of the ejector to the lowermostpackage of goods; a goods receptacle; and means secured to the goodsreceptacle for guiding the outer portion of the ejector.

4. In a goods ejector for vending machines, the combination of twoyieldingly lpivoted portions; a block secured to a slidable plunger;said plunger; the inner portion of the two yieldingly pivoted portionsbeing pivoted to the block; a spring for holding said portion in itsupward position; means for limiting the upward movement of said portion;an outer portion rotatively pivoted to said inner portion; means forguiding the outer portion to limit its vertical movement; and meansco-acting with the said inner portion to lock the plunger inwardly .whenthe last package of goods has been ejected.

In witness whereof, we have hereunto set our hands, in the presence oftwo subscrib-` ing witnesses, this the 4th day of February,` l
